I built a fiberglass shroud to run a 14" electric fan, just wondering what CFM are yall running? Looking at 1900-2200 CFM fans right now.

i dont know the exact #s, but im running the big single OE 2 spd ford Taurus fan. Ive seen "tested" claims of 2800cfm low/5600cfm high @ bat voltage, and 3200cfm low/6000cfm @ alternator voltage.


i just have it wired to low speed only via a manually operated switch/relay combo

Yeah, I wheel and deal with Taurus fans(probably sold 15 of them lol). I rock crawl and they are a pretty common swap. Most guys I know with them never even use the high speed.

I made the shroud and want to stick to a 14" fan. I would think 2200cfm would be plenty. Just making sure.

well, ive never come close to overheating running just the low speed , so i think 2200cfm should be up for the task, unless you have a huge turbo, inadequate radiator and terrible heat shielding. :P

most people dont use the high setting for 2 reasons. no need, and/or the cost of running a dual relay circuit in parallel (i.e. 2x as expensive to wire) for the high speed

I'm running a 14" 1800 CFM fan right now in my car and its cooling it well enough.

I have a water temp gauge with the sensor right outside the thermostat and I haven't seen this setup run above 185 or 190 since it's been installed. So I'm pretty satisfied with it

I have a vented hood, so that should help with heat issues also.
The fan will be blowing a lot of the heat from the radiator out, when stopped.
